Hi,

the link to the patch does not work anymore. There’s a new version of the patch available at http://www.pcguild.com/updates/LeopardJavaPatch_V2.zip

Cheers

Thanks Florian - I updated the link in my post. I should have remembered to update it since I work at PC Guild and am the person who created the patch! FYI, anybody who is trying to install the new patch and gets a permission error - you now have to close all programs (including your browser) before installing due to some Java files that are in use when your browser is open.

Hmm, I am curious what is in the patch now. I thought I could just copy the 1.3.1 folder from Tiger to Leopard but when I tried that it didn’t work. Your patch also install a folder called ‘A’, what’s the magic in it?

Thanks for sharing.

Hey Peter, the version numbered folders are the Java core classes, whereas the “A” folder contains the actual Java runtime implementation for OSX.

Apple releases a system update around april ‘08 which added Java 6 and updated the “A” folder - which broke the backwards compatibility with Java 1.3.1. So the V2 patch simply contains the “A” folder exactly as it was just prior to that system update.

So V1 of the patch was completely safe because it was just adding some missing files. V2 actually downgrades the runtime. Unfortunately I can imagine this will eventually cause some problems with Java 6 applications, but thus far I have not heard any problems reported.
